Notice to our Canon mount lens users [Update]

As same as the Live View mode of Canon “EOS 8000D (Rebel T6s / 760D)” and “EOS Kiss X8i (Rebel T6i / 750D)”, we have found that similar update is required for our lenses to make them compatible with the Live View mode of “EOS 5Ds” and “EOS 5Ds R” cameras.

* For lenses that have been repaired in the past, they may require the firmware update even when the serial number is not listed above.
If the mentioned camera does not display images on the rear LCD monitor when Live View Mode button on the camera body is pressed, it is necessary to update the firmware.
* Our DC lenses are developed for the camera bodies with APS-C image sensor, and it is not designed for the cameras with full-size and 1.3x sensors.
* There is no need to update the firmware of those products shipped after May 11th in 2015 or already updated for Canon “EOS 8000D (Rebel T6s / 760D)” and “EOS Kiss X8i (Rebel T6i / 750D)”cameras.

For those who own the SIGMA USB DOCK, it will be possible to update the firmware of 120-300mm F2.8 DG OS HSM | Sports through SIGMA Optimization Pro.

* If you use the SIGMA USB DOCK with 120-300mm F2.8 DG OS HSM | Sports, even when the lens does not require the update, its firmware will be updated to the new version.
